  • Publication number: 20140076838
    Abstract: A plastic container with a cut neck is disclosed, which is produced by stretch blow-molding from a preform manufactured by plastic injection or plastic flow molding, and which immediately following production, or separated in space and/or time, is inserted into a mold cavity of a blow-mold tool of a stretch blow-molding device and with the aid of a blow-molding medium inflated and stretched according to the mold cavity. The preform is then shaped to form the desired plastic container by cutting off an excess section that includes an injection-molded neck part of the preform.

  • Publication number: 20140042673
    Abstract: An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having upper and lower die sets and a plurality of upper and lower mold half blocks each attached to a respective die set. Each of the upper mold half blocks has a corresponding lower mold half block with which it cooperatively defines one or more cavities for forming the exterior shape of the body of one or more of the parisons. The individual, independent attachment of the mold half blocks to the die sets allows easy individual replacement of faulty or worn mold blocks. Further, such an independent attachment configuration also permits the mold half blocks of each die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the mold half blocks.

  • Patent number: 8632722
    Abstract: A blow molded synthetic resin bottle has a body and an elongated neck with the body providing a shoulder extending about the base of the neck. The neck has a first collar extending thereabout spaced adjacent the shoulder and at least one additional collar extending thereabout adjacent the upper end of the neck. The resin in the neck is substantially unoriented. To produce the bottle, a synthetic resin preform is injection molded with a generally tubular body and the elongated neck. This preform is placed in a blow mold cavity having a body receiving portion and a neck receiving portion that has a recess extending thereabout seating the first collar therein. The additional collar is disposed outwardly of the mold cavity and is disposed on the upper surface of the mold.

  • Patent number: 8617454
    Abstract: A method for manufacturing a resonator is disclosed in which a sleeve insert is placed into a fixture within a blow molding apparatus. The sleeve insert has a wall with a first plurality of apertures in the wall at a first axial distance and a second plurality of apertures in the wall at a second axial distance. A parison is slid over the sleeve insert; the mold is clamped over the parison causing the parison to press into the sleeve insert at three locations: near the ends of the sleeve insert and at a location between the pluralities of apertures; and air is blown into the sleeve insert, via a blow pin, to expand the parison into the walls of the mold to form cavities proximate the first and second pluralities of aperatures. After cooling, the mold opens to release the newly formed resonator.

  • Publication number: 20130328249
    Abstract: The invention relates to an installation and a method of producing hollow bodies by injection molding and subsequent blow molding. The installation comprises an injection molding tool with at least one cavity for producing a preform with a neck continuation and a hollow body part adjoining the neck continuation, a blow mold for shaping the hollow body from the preform and transfer means for transporting the preform from the injection molding tool to the blow mold. The transfer means comprises a carrying frame in which at least one holding element for the at least one preform is disposed. When transferring the preform from the opened injection molding tool to the transfer means, the preform is held on the outside of its neck continuation by a tool part of the injection molding tool and is thereby removed from the cavity. The preform is then placed with the inside of its neck continuation into the holding element, such that the holding element bears against an inner surface of the neck continuation.
